COleServerItem::OnRenderFileData
Called by the framework to retrieve data in the specified format when the storage medium is a file.
virtual BOOL OnRenderFileData(
LPFORMATETC lpFormatEtc,
CFile* pFile
);
Parameters
lpFormatEtc
Points to the FORMATETC structure specifying the format in which information is requested.pFile
Points to a CFile object in which the data is to be rendered.
Return Value
Nonzero if successful; otherwise 0.
Remarks
The specified format is one previously placed in the COleDataSource object using the DelayRenderData member function for delayed rendering. The default implementation of this function simply returns FALSE.
This is an advanced overridable. Override this function to provide your data in the requested format and medium. Depending on your data, you might want to override one of the other versions of this function instead. If you want to handle multiple storage mediums, override OnRenderData. If your data is in a file, or is of variable size, override OnRenderFileData.
